Hi! The controller is base on MIDIBOX64E, it has 64 button, 40 potentiometer, 16 Encoders, 48 leds, 1 lcd. Once I finished the structure I uploaded the last MIOS mios_update_v1_9f.zip using MIDI-OX, this is the Operative system. After that I uploaded with MIOS-studio the midibox64 application from midibox64e_v2_2b.zip download section of ucapps. I don't know anything about programming, the only code I need to change was for the encoder to change to detent mode. Using sarge editor for MIDIBOX64E I assigned commads or note to every component and I connect DOUT (led) to MIDIEVENT to let Traktor send output signal and light the leds. The controller is working good with traktor PRO. I connected the midi in midi out to NI kontrol 1 audio interface. I noticed that once I used the buttons on the audiointerface that send midi signal on another channel, my midibox start to have problem of comunication. Problems like: I move a pot to value eg. 65 after that when I move another the last change it's value to 66. This also happens with button and leds. To solve this problem I connected the midibox with a usb to midi converter and turn off midi signal of the NI kontrol 1. This solves the problem for a period, but it happens again randomly, to solve it I disconnect the usb to midi converter and plug it again. I think the problem comes from the computer and not from midibox. Any ideas? sorry for the bad english. Regards Alessandro
